which it appertains to make and use the same.

his invention relates to a novel constructioi. in a pipe clampparticularly adapted for use as a temporary means for stopping leakscaused hv cracked )ipes or by reason of sand holes and the like therein,the object being to provide a simple and ellicient device of thischaracter which can be easily and quickly applied and consists infeatures of construction and combinations of arts hereinafter fullydescribed and claime In the accompanying drawings illustrating theinvention Figure 1 is a transverse section of a pipe clamp constructedin accordance with my invention showing the same disposed upon a pipe.Fig. .2 is a side elevation of the same. Figs. 3 and 4 are respectivelyan end and inner face view of one member of the clam The sole object ofmy invention is to provide a pipe clam for repairing leaks in pipeswhich consists o two members identical with each other and castfrom thesame pattern and which are adapted to interlock with each other at oneedge portion and be easily sccured together by bolts at the other edgeportion whereby said members are not only ren- .dered convenient of useand the necessity of pairing avoided but are also rendered cheapertomanufacture th invention residing most particularly in the specificform of interlocking means employed.

My said clamp consists of two equal sub stantially semi-cylindricalmembers A and B each of which is provided on its long edges with flangesand 1) respectively. The said flange is provided with a plurality ofprojections E having reces es I therein for the reception of bolts G bvmeans of which said members are secured together at one side..

Zach of said flanges D of said members is provided with a longitudinalslot II ad acent one end and adjacent the other end thereof with a hookJ projecting from the inner face of said flange, the latter being cutawa I as at K in alinement with the free end of Sl1i( hook.

\Vhen said members A and B are opposedv the hooks J of each is adaptedto enter the slot II in the flange of the other thus interlocking saidmembers on said edge. The said members A and B are adapted to receiveand embrace the pipe L and a stri of rubber or other suitable mcking Mwhic 1 is clamped and firmly held by said members A and B in contactwiththe leaky portion of the pipe to -seal such leak in a well-known Imanner. One of said members A or B may be Provided with a nipple N toreceive a rod or the like thus adapting the device. for use as a ipchanger. I do-not however, contemp ate-providing said nipples as saidmembers would seldom if ever, be employed for such urpose. Both saidmembers A and B are it entical and cast from a single )attern andhy'reason of the recesses F the bolts with the nuts in place may be droped into the same and by a. few turns of salt members toward each otherso as to firmly compress the packing against the pipe. The operation isthus rendered very easy and rapid and annoyance arising from dropping ofnuts, etc.,

is largely avoided. The said members A and B are preferably provided attheir ends with peripheral flanges O to reinforce the same.

I claim as my invention: 1. A pipe clamp consisting of two equalsubstantially semi-cylindrical members eaclc stantialy semi-cylim ricalmembers each PIOYltlCt on its long edges with flanges, one

flange of each being provided with a slot adjacent one end, a hookprojectingfrom said slotted flange adjacent its other end and adaptedwhen said members are opposed to enter the slot in said flange of saidother member to interlock said members on said edge ortion, said otherflanges of said memname in presence of two subscribing witbers ei'ngnrovided in their free ends with nesses: recesses and bolts enteringsaid recesses, and enga ing said flanges to secure said members 5together and draw the same toward each Vitnesses: A. other to contractthe same on a pipe.
